It loses lock on the CTCSS during the 180 degree phase shift,

You can make the measurement with a signal generator and a tunable receiver
that has some kind of indicator for signal strength. It doesn't even need to

I read the MTR2000 with my laptop. Sure enough, it has the 150-174mhz 100w pa.
However, I noticed in the software that the exciter is listed as 132-174mhz AND
the PA is an option. Does this mean I could disable the PA and run an external
PA, such as a MASTR II or MSR2000?

Hello All,
I have on the bench into a dummy load an exceptionally clean Mastr II
100 watt UHF PA. It appears to be a late model version because it has
the Z-Match board right above the RF output connector.
At 13.6 volts and 21 amps, it's doing 100 watts easily. I can vary it
down all the
first thing i would check would be aging solder joints, all the expansion and
contraction due to heat and cold can make them loose integrity.

Very discouraging results if you expect a BPBR duplexer to provide
In addition to checking the solder joints on the transistors, check the

This is wonderful information! So the bottom line is for duplex operation, a
pass/notch is needed to protect the rx and tx from each other, but for
everything else a bandpass-only filter is the way to go.
